  • a part of the magnified image is not simultaneously displayed on the preview window 301 .
  • a user is allowed to confirm the hidden part by operating scroll bars.
  • the client PC 200 When the client PC 200 receives a printing/transmission execution instruction from a user (Step S 55 ), the client PC 200 causes the communication unit 201 to transmit the printing/transmission execution instruction to the server 2 (Step S 56 and Arrow i of FIG. 1 ).
  • the preview editing section 23 b of the server 2 edits the same magnification image data III based on the contents of the instruction (Step S 63 ).
  • the preview editing section 23 b reduces the same magnification image data III at 50% magnification (see FIG. 12 ), and suitably executes editing in accordance with other conditions.
  • a preview image data III′ is generated.
  • the preview editing section 23 b edits the maximum magnification image data II based on the instruction contents (Step S 64 ). In other words, when the specified magnification is 200%, the preview editing section 23 b reduces the maximum magnification image data II at 50% magnification (see FIG. 12 ) and suitably executes editing in accordance with other conditions. Thus preview image data II′ is generated.
  • the preview editing section 23 b generates a preview image by reducing the base image data.
  • the phrase “by reducing” may be herein replaced by the phrase “without magnifying the once-reduced image data”.
  • the preview editing section 23 b is allowed to generate preview image data reflecting the image editing instruction from the client PC 200 by executing a variety of editing (e.g., color, density, and rotation of an image) excluding change of magnification (enlargement/reduction).
  • a variety of editing e.g., color, density, and rotation of an image
  • the server 2 feedbacks the editing result by the preview editing section 23 b to the client PC 200 through the communication unit 21 (Step S 65 and Arrow iv of FIG. 1 ).
  • the client PC 200 receives the editing result, that is, a new preview image, it executes Step S 51 and the subsequent steps in the flowchart of FIG. 9 again.
  • the communication control section 23 a causes the communication unit 21 to transmit the contents of the image editing and the printing/transmission execution instruction to the MFP 1 (Step S 67 and Arrow ii of FIG. 1 ).
  • the MFP 1 receives the image editing conditions and instructions to execute printing/transmission from the server 2 (Step S 71 ), the MFP 1 causes the sections to perform a variety of processing.
  • the MFP 1 causes the image processing section 16 d to process (edit) the original image data I in accordance with the received conditions (Step S 72 ), and causes the printing unit 11 to print out the processed image or causes the communication unit 12 to transmit the processed image (Step S 73 ).
  • image processing such as printing and transmission is executed based on the contents of the image editing instruction.
  • the printing control section 16 a controls a printing operation of the printing unit 11 (e.g., selection of printing paper) while setting the image editing instruction provided by the server 2 to a printing condition.

  • the MFP 1 is configured to execute other image processing such as facsimile transmission.
  • the image processing system 100 of the present embodiment is configured to provide the client PC 200 with a preview image. Additionally, in generating a preview image, the MFP 1 generates the base image data while the server 2 generates a final review image by editing the base image data. Thus, the server 2 is in charge of a part of preview image generation processing. Accordingly, processing speed will be enhanced and data capacity processed by the MFP 1 will be reduced compared to preview image generation processing executed only by the MFP 1 .

  • the original image is first reduced and is then magnified.
  • reduction of the original image requires resampling processing. Accordingly, deficits arise in spatial frequency of an image.
  • the present embodiment is configured to generate a preview image without magnifying the once-reduced original image. Therefore, it is possible to provide a preview image with fine image quality.
  • control unit 16 of the MFP 1 it is possible to form the control unit 16 of the MFP 1 , the control unit 23 of the server 2 , and the control unit 205 of the client PC 200 by central processing unit (CPU), read-only memory (ROM), random access memory (RAM), and the like.
